Model test device and method for measuring ultimate bearing capacity of pile group under inclined eccentric load in sandy soil
The invention provides a model test device and method for measuring ultimate bearing capacity of pile groups under inclined eccentric load in sandy soil, the device is based on a model box, a plurality of model pipe piles with notches are arranged in the model box, strain gauges are arranged in the model pipe piles, the outer side of the upper part of each model pipe pile is sleeved with a test bearing platform, and the upper part of each test bearing platform is provided with a test hole; sandy soil falls below the test bearing platform; the pipe pile side surface at the top end of the model pipe pile and the contact part of the bottom plate of the test bearing platform are fixedly adhered through a hot melt adhesive to form a model pile group anti-pulling test device; and high-strength gypsum is poured between the top of the model tubular pile and the top plate of the test bearing platform to form the model pile group compression test device. The device has the advantages of being simple in structure, convenient and fast to operate, wide in application range and capable of being recycled, and stress deformation rules of various model group piles under the inclined load can be conveniently studied.
本发明提出一种砂土中倾斜偏心荷载下测定群桩极限承载力的模型试验装置及方法，该装置以模型箱为基础，所述模型箱内设有多个带有切口的模型管桩，所述模型管桩内设有应变片，所述模型管桩的上部外侧套设有试验承台，所述试验承台下方落砂土；模型管桩顶端的管桩侧面和试验承台的底板的接触处通过热熔胶固定粘连，构成模型群桩抗拔试验装置；所述模型管桩的顶部和所述试验承台的顶板之间浇筑高强度石膏，构成模型群桩抗压试验装置。本发明的研究具有结构简单、操作便捷、适用范围广、可循环使用的优点，可以方便地进行各类模型群桩在倾斜荷载下的受力变形规律研究。
